| titleOfInvention | Carbon tube array honeycomb surface shape precision calculation method based on G code processing guidance |
| abstract | The invention provides a carbon tube array honeycomb surface shape precision calculation method based on G code processing guidance. The invention comprises the following steps: acquiring a measurement G code which is consistent with the surface contour of the design model; measuring the surface shape data of the carbon tube array honeycomb for multiple times by using a line laser device to generate a plurality of three-dimensional point cloud data; splicing and denoising the acquired multiple pieces of point cloud data to obtain a complete surface shape of the surface of the workpiece, and storing the complete surface shape as measurement point cloud data; obtaining new position point cloud by matrix transformation of the measured point cloud data according to the initial position information of the G code, and roughly registering a design model with the new position point cloud; and projecting the new position point cloud onto a surface patch of a design model to obtain model point cloud corresponding to the number of the point clouds to be measured, registering, calculating the length of a vertical line from the point cloud to the corresponding surface patch to obtain an error length set, and calculating the surface shape error according to the error length set. The method has high contact ratio between the measured point cloud and the model, and is suitable for various curved surfaces which are difficult to measure. |
